Ubuntu Nvidia no TTY

[aceralex]

Hi all,
i am running ubuntu 10.10 with awesome and gnome (gnome for testing reason). I have the problem that i can't change from my Windowmanager (Awesome + Gnome , both are affected by this problem) to any tty (Displaymanger Slim). All tty's are listed on /dev as they should.
A change to any tty cause all sound (pulseaudio) to stop till i change back to wm (alt + ctrl + f7) and then when i hit return slim crashes. Sometimes then i see a lot of black squares in screen and blinking cursor (i guess from tty in background). I am using slim as displaymanager.

I also tried gdm with a different behaviour regarding that problem:
In gdm i am able to switch to tty but when i watch flash in fullscreen and switch of fullscreen the last movieframe is freezed on some parts of the windowmanager's gui (desktop, panel etc).

I figured out, that booting in single user mode (grub -> single) fixes the strange behaviour. This strange behaviour is hard to describe, i hope anyone has a similar problem/experience.

Thanks in advance.

The following Screenshot attached shows the Problem after using the flashplugin in my browser. The black area, showing the flash movies's last picture remains after closing the flashplayer. In a screenshot via scrot it doesnt appear, so i took a photo of my screen.

Check the behaviour if you run the default open source driver for Nvidia devices instead of the proprietary one, by replacing "nvidia" with "nv" in /etc/X11/xorg.conf. How did you install the driver, via "Additional Drivers" or in another way?

hi,
i installes the "original" nvidia drivers via apt-get install nvidia-current.

cheers.

Ok, that explains some! Switch to the "nv" driver as mentioned.
Then remove that package with:

sudo apt-get remove --purge nvidia-current
Then install it again via "System -> Administration -> Additional Drivers", which will pull in some other packages.

After that, and hopefully a successful reboot, save the configuration to the "xorg.conf":
- go to "System -> Administration -> NVIDIA X Server Settings"
- click at "X Server Display Configuration" on the left side
- check/choose your desired configuration
- click at "Save to X Configuration File"
- enter your "root"-password when asked
- choose replace, not merge!

ok, but i need 3d acceleration, does it works with the nv driver?

Nope, that's why you to do the other steps as well.;)

[aceralex]

okay thanx, now i got it :D
i will try and post my experience with that

[aceralex]

ok, i was able to fix closely everything. after following your instruction, xserver failed to start with various errorlogs. the i installed the latest nvidia-driver from ubuntu-x-swat. that did it, now i am able to use my tty's and everything's fine except *surprise' flash !

But the reason for that failing is flash itself because of its failing ..... time for webm xD

just for your amusement, the latest behaviour of flash :popcorn:

thanx for your help and inspiration, krytarik 8)

Yeah, Flash definetely sucks, it's overly heavy CPU-consuming. I tend to give Apple right to not supporting it. Although I don't have such a mess like you in the screenshot. You may try those guide, altough it doesn't work for me, maybe because I've a bit old hardware setup:

hi,

good news, flashplayer 10.1.102.65 sucks a bit less, it works as you can call flash working, no burned frames and blacksquares anymore.

Oh, I already had those version, I assumed that you also had the most recent updates.
I checked the log of apt, it has been installed exactly at 2010-11-19 at my machine.[-X ;)

If you want to mark this thread as "solved", do it via "Thread Tools", thanks.

That makes indeed totally sense, I didin't take that into account, Adobe's development of the 64-bit Flash plugin is lagging behind those of its 32-bit version.

That also explains the major difference of its performance between your and my machine.

Adobe states to have a preview version here: http://labs.adobe.com/downloads/flashplayer10.html . I only get 32-bit versions displayed there, I suppose because my browser reports itself at 32-bit.

If that URL doesn't work for you also, here is another one, same version:
http://fileforum.betanews.com/detail/Adobe-Flash-Player-for-Linux/964714156/4

This should provide a considerable performance increase, because of its native 64-bit support.

The version you are currently getting through the repo is imo just a port to 64-bit.
